为了探讨农田防护林带对农作物生长发育的影响及其增产情况,我们于1983年在布海乡进行了调查。布海乡位于德惠县南部雾开河南岸,总土地面积151,500亩,耕地面积106,200亩,属我省一般风害区。该乡从1972年到1983年共造农防林16,332亩,构成农田林网231个,森林复被率达11％。对改善当地的自然气候条件起到了明显作用(见表1),粮食连年增产,农副业生产兴旺发
In order to investigate the impact of farmland shelter belts on the crop growth and development and its yield increase, we conducted a survey in Buhai in 1983. Buhai Township is located south of Wakai River in the south of Dehui County, with a total land area of 151,500 mu and arable land of 106,200 mu. It belongs to the general wind damage area in our province. The township made a total of 16,332 mu of agricultural anti-forest activities from 1972 to 1983, constituting 231 forest farms and 11% of the forest rehabitation rate. It has played a significant role in improving the local natural climatic conditions (see Table 1). Grain production has been increasing year by year and the production of agricultural and sideline products has been flourishing
